Abb TC300 Raintight Hub 3 Inch Load Center

Product Description

The ABB TC300 is a universal raintight hub designed for use with outdoor electrical enclosures, load centers, and panelboards. Rated for outdoor installation, it provides a weatherproof conduit entry point that helps protect wiring connections from moisture and environmental exposure. The TC300 features a 3-inch hub diameter and a 3-inch base size, making it suitable for applications requiring a secure, watertight conduit fitting at the enclosure knockout. Licensed electricians typically specify this fitting when installing or servicing outdoor panels where raintight conduit entry is required by code.

This hub is intended for use with ABB Mini Mod and TDT series load centers and panels. Its universal raintight design accommodates a range of outdoor enclosure installations in both residential and light commercial electrical systems. The fitting is selected when conduit terminates at an outdoor enclosure and a weather-resistant entry seal is needed to maintain the integrity of the enclosure rating.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the panel and verify absence of voltage before beginning work on any enclosure or conduit fitting. Ensure the knockout size matches the hub base before installation, and verify the conduit system is compatible with the fitting thread and seal type. Do not overtighten the locknut, as this may compromise the raintight seal or damage the enclosure wall.
